LATHlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 593,864, dated November16, 1897. I Application filed November 5, 1895. $eria1No. 568,045. (Nomodel.)

To all whom it may concern:

Be it known that I,.IOHN G. STAUDENMAYER, a citizen of the UnitedStates, residing at Allegheny, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inLathin g Machines; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to certain new and useful improvements inlathing-machines;

and it has for its object, among others, to provide a simple, cheap,durable, and portable device which can be readily attached to suit thecircumstances to which it is desired to employ it and by which the nailsmay be readily driven. I also provide a cutting attachment whereby thelath may be sawed any desired length.

Other objects and advantages of the invention will hereinafter appear,and the novel features thereof will be particularly pointed out in theappended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisspecification, and in which- Figure 1 is a side elevation of my improvedapparatus. Fig. 2 is a view looking at the opposite side. Fig. 3 is anenlarged sectional detail of the nail feeding and driving apparatus.Fig. 4 is a detail view of the same in plan. Fig. 5 is a perspectiveview of the claws removed. Fig. 6 is a perspective view showing theapparatus set up in position for use and clamped between the floor andceiling.

Like letters of reference indicate like parts throughout the severalviews.

Referring now to the details of the drawin gs by letter, A designatesthe base of the machine, from which rises the vertical standard A, tothe upper end of whichis secured the horizontal guide-bar A. The machinemay be supported in the desired position and there held by set-screws aand braced vertically by the vertically-adjustable brace A having aT-head adapted to engage the ceiling-joist or other suitable means.

B is a foot-lever pivotally mounted at one end, as at b, and its otherend has pivotally connected therewith the rod B, to the upper end ofwhich is connected one end of a spring B the other end of which isdetachably engaged with a hook b, depending from the horizontal guiderod or bar.

O and O are vertically-disposed toothed rods or rack-bars mounted formovement in suitable guides,'as shown. The lower ends of these rackshave pins playing in the vertically-slotted uprights of the frame A andin slots disposed longitudinally of the treadle B, as shown best in Fig.1.

D is the striking-hammer, pivotally mounted, as at d, on the horizontalarm E, which embraces the standard and is adapted to slide verticallythereon. Carried by this horizontal arm is a nail run or carrier F.

f is a nail-regulator which, being arranged as shown best in Figs. 1, 3,and 4, serves to govern the movement of the nails and to keep themstraight, so that they shall be presented properly to the shank andhooks of the hammer. This carrier or run extends over the funnel G, andthe slot therein terminates at a point in line with said funnel, whichlatter is arranged in position to receive the falling nail from said runor carrier, thelower end of the slot of which is enlarged, as seen inFig. 4, to permit of the ready passage of the nail when it reaches suchpoint. This funnel has its lower end extending down to the claws g,which are adapted to hold the nails firm until they are acted upon bythe nail set or pusher. The lower claw is held upward by means ofsprings g. (Seen best in Fig. 3.) The lever and pins indicated in Fig. 4form a picker mechanism for letting one nail at a time drop. Mounted onthis arm E is also the nail set or pusher H, mounted to reciprocate insuitable guides on said arm and retracted against the action of thehammer by a spring h. (Seen best in Fig. 1.) This nail-regulator servesto govern the movements of the nails and to keep them straight, so thatthey shall be presented properly to the finger and hooks of the hammer.

At the lower end of the machine is shown a horizontally-projecting armI, having a series of openings which provide for the regulation of thespaces.

J is the lath-holder, pivotally mounted on the outer end of the arm E. Jis thespacer,

also carried by the said arm, as seen best in Fig. 2. This latter isregulated by means of the slotted arms jj and the spring j as seen inFig. 2.

K is the nail-box or nail-reservoir, arranged above the nail-run ornail-carrier, and from which box the nails feed automatically into thecarrier.

L is a pivoted stop or pawl adapted to engage the rack-bar X, which isdisposed between and at right angles to the rack-bars O 0', thus holdingthe arm in its adjusted position. Pawl L is mounted upon the arm E. Uponthe rack-bar C is mounted a saw M, which may be employed for sawing offthe laths when necessary. The other rack-bar G serves to actuate thehammer and also to reciprocate the saw by which laths may be out offwhen desired.

In operation the arm E will rise inch by inch the distance between thelaths at each upward motion of the foot-lever, and when it reaches thetop it can be quickly dropped by disengaging the pawl from the rack-barO. The lath is firmly held by the lath-holders until the nail is driven.After a nail has been driven by the hammer the nail set or pusher isretracted by its spring and another nail falls into the jaws from thefunnel in position to be driven by the next upward movement of the nailset or pusher. The apparatus can be readily adjusted to accommodateitself to the varying distances between the studding and can be usedupon a scaffold as well as upon a floor.

Modifications in detail may be resorted to without departing from thespirit of the invention or sacrificing any of its advantages.

\Vhat- I claim as new is 1. In combination with a base and upright, ofthe horizontal arm mounted to slide on said upright, the nail feedingand driving mechanism, mounted on said arm, the vertically-movablerack-bars and a pivoted footlever connected with said rack-bars,substantially as described.

2. The combination with a base and upright of a horizontal arm mountedto slide on said upright, a nail feeding and driving mechanism mountedon said arm, the vertically-movable rack-bars and a pivoted foot-leverconnected with said rack-bars and a retractingspring connected with saidfoot-lever, substantially as described.

3. The combination with the base and the upright, the rack-bars, thepivoted foot-lever connected therewith and a spring connected with saidfoot-lever, of a pivoted hammer on said arm and a nail feeding, guiding,holding and driving mechanism mounted on said arm, substantially asdescribed.

4:. The combination with the base and the upright, the rack-bars, thepivoted foot-lever connected therewith and a spring connected with saidfoot-lever of a pivoted hammer on said arm, a nail feeding, guiding,holding and driving mechanism mounted on said arm and a lath-holdingmechanism also mounted on said arm, substantially as described.

5. The combination with the base and the upright, the rack-bars, thepivoted foot-lever connected therewith and a spring connected with saidfoot-lever, of a pivoted hammer on said arm, a nail feeding, guiding,holding and driving mechanism mounted on said arm and a lath-holdingmechanism also mounted on said arm and means for adjusting the latter,substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

JOHN G. STAUDENMAYER.
